A measure of the relationship between two variables that avoids this difficulty is the correlation coefficient, sometimes called the Pearson product moment correlation coefficient. Excel provides a data analysis tool, called CORRELATION, and two statistical functions, called CORREL and PEARSON, that compute this numerical measure.

Correlation Coefficient. The Correlation Coefficient is calculated according to the following formula: We would build a complicated formula like this in steps – incrementally - having broken it down to its component parts, each of which could be written simply using standard Excel features. We will construct this formula in the training session.

The correlation coefficient will appear in that cell. Note: This assumes you have 20 rows. If you have 30 rows, the command will look like this: =pearson(a1:a30,b1:b30) Excel will also draw the scatter plot: Go to Insert/Chart and pick XY Scatter, then Next. Under data range, type “=a1:a20,b1:b20” (for this example).
